Do not worry, there is now a new program developed by the team leader David Forsyth of the University of Illinois, Urbana-Champaign who managed to create change by simulatingthe lighting conditions so that changes to look realistic.
To generate such a level, this new software first to engineer a three-dimensional (3D) where the picture was taken.
A user asked to select the source of light in the picture so that an algorithm can createmore 3D geometry and lighting a picture and insert an artificial object into his newenvironment.
This graphics program then adds shadows and highlights to the object before it is converted back into 2D. Light level object then analyzed and adjusted to the conditions inthe image before it is inserted.
Photo editing programs that currently exist can only insert 2D objects without considering the lighting and the perspective of artificial objects and photographs.
"People can quickly detect the photo hoax because we can accurately place the inconsistency lighting in a photograph," says Kevin Karsch, a member of the team.
The researchers hope the new program is beneficial in manipulate data by adding thehistorical artifacts at the old photos.
The new program is also useful for interior design because it allows the pendekorasi takeone photo in one room and virtual experiments with different furniture.
These creative works will be presented at SIGGRAPH Asia, special conferencescomputer graphics and interactive techniques, on 12-15 December in Hong Kong.
